DMA, or dimethoxyamphetamine, is a series of lesser-known psychedelic drugs similar in structure to amphetamine and to trimethoxyamphetamine (TMA). They were first collectively charictarized by Alexander Shulgin in his book PiHKAL (Phenethylamines I Have Known And Loved).[1] Little is known about their dangers or toxicity.

Positional isomers[edit]


2,4-DMA, or 2,4-dimethoxy-amphetamine

  • Dosage: 60 mg or greater
  • Duration: "Probably short."
  • Effects: stimulative, amphetamine-like effects


2,5-DMA, or 2,5-dimethoxy-amphetamine

2,5-DMA is the alpha-methyl homologue of 2C-H and could be called "DOH" under the DO naming scheme.


3,4-DMA, or 3,4-dimethoxy-amphetamine

Note that two other positional isomers of dimethoxyamphetamine, 2,6-DMA and 3,5-DMA, have also been made, but these drugs have not been tested in humans and their effects are unknown. However, it is likely that these compounds would also produce amphetamine-like stimulation or possibly hallucinogenic effects.

Legal Status[edit]

United States[edit]

2,5-dimethoxyamphetamine is listed as a Scheduled I controlled substance at the federal level in the United States and is therefore illegal to buy, posses, and sell.[4] 2,4-dimethoxyamphetamine, 2,6-dimethoxyamphetamine, 3,4-dimethoxyamphetamine, and 3,5-dimethoxyamphetamine are each position isomers of 2,5-dimethoxyamphetamine, they are therefore all Schedule I controlled substances as well.
